标题： Considerations on electromagnetic radiation in Podolsky electrodynamics within a Lorentz-symmetry violating framework

摘要： 我们探讨了高阶导数项在洛伦兹对称性破坏（LSV）框架内对物理可观测量的影响。 我们特别检查了与卡罗尔-菲尔德-杰克伊模型（CFJ）耦合的波多尔斯基电动力学。 我们的分析显示，真空和波传播如何受到LSV参数与波多尔斯基电动力学特性相互作用的影响。 在这种情况下，我们的结果表明，新的电磁真空具有双折射、双色性和色散性。 我们还指出，在CFJ时空各向异性存在的情况下，高阶导数项会引发光子（获得非零质量）与由高阶导数携带的大量矢量模式之间的振荡机制。 随后，我们研究了与这种新介质相互作用的运动带电粒子发出的电磁辐射。 我们的分析揭示了带电粒子通过的折射真空会影响电磁辐射，导致类似于切连科夫效应的分布。 显示英文摘要

摘要： We explore how higher-order derivative terms impact a physical observable within a Lorentz-Symmetry Violating (LSV) framework. We specifically examine Podolsky electrodynamics coupled with the Carroll-Field-Jackiw model (CFJ). Our analysis shows how vacuum and wave propagation are affected by the interaction of LSV parameters with properties of Podolsky electrodynamics. In this scenario, our results indicate that the new electromagnetic vacuum is birefringent, dichroic, and dispersive. We also point out that the higher-derivative term in the presence of the CFJ space-time anisotropy induces an oscillation mechanism between the photon, which acquires a non-vanishing mass, and the massive vector mode carried by the higher derivative. We then investigate the electromagnetic radiation emitted by a moving charged particle interacting with this new medium. Our analysis reveals that the refractive vacuum through which the charged particle travels influences the electromagnetic radiation, leading to a profile similar to the Cherenkov effect.
